Toall wltmft may concern.' f

lBeit l''iow 'that I, WI'LFRED C. PARRY, a citizen of the United States,and a resident' of Marble, in 'the count of `Gunnison and State ofColorado, have invented a new and ImprovedMetal Railroad-Tie, of whichthe following is a full, clear, and exact descriptIox'r.

This invention relates to railway 'equipment and has particularreference to crossties for railway rails. f

VAmong the objects of the invention is to construct a railway .tierinci'pally of metal and 'provided with "easi y operated and reliablerail clamping devices.

The foregoing and other objects of the inventioh w' l drawings forming apart of. this specificaand in which- Figure 1 1s a transverse sectlon ofa rallroad track indicating one of my improved crossties in side view;Fig-2 is a longitudinal section of the crosstie on the line 2-2 of Fig.3 ;,Fig. 3 is a plan view of the same;

Fig. 4 is an end view; Fig. 5 is 1a transverse .sectional view of thecrosstie on the line 5-5 of Fi 3; Fig. 6 is a perspective View of one oft e rail plates; Fig. 7 is a artial horizontal section on the line 7 -7of ig. 5; and Fig. 8 is a detail of on'e of the rail braces or clamps.

The several parts of the device may be made of any suitable materials,and the relative.`sizes and proportions, as well as the general designof the mechanism, may be varied to a considerable extentV withoutdeparting from the s irit of the invention hereinafter more ully.described and specifically claimed.

Referring more particularly to the drawings, I show a preferredembodiment of my tie' at 10,l the same being shown assubstantiallytubular in form and rectangular in` cross section. The endsof the tie are open, and except as herein later s'et forth the interiorof the tie is hollow. Adjacent each end of the upper portion of the tieis provided a seat 11 for a rail R. Said seat is rail.

l hereinafter be more fully cle-- `scribed and claimed and illustratedin the formed preferably by removing a portion of edgeo the seat beingundercut, forming a lip 12 adapted to overlap the base iian e of therail, and thereby preventing the t' ting of the rail inwardly toward theopposite The inner side of the seat 11 or the edge opposite the lip 12is far enough remote to allow ample room for introducing the rail andclamping devices. The rail brace 13, shown in 'detail in Fig. 8,comprises preferably a hollow box-like structure having ,on its bottomoutwardl projecting ianges 14.- which are adapted t'o project beneath apair of shouldersl eirtending parallel to each other and to thelplrgitudinal axis of the tie outwardly from the lip 12. As shown in Fig.`8, the Han 1 4 may be formed by bending the vertic'a sides 16 of thebrace 13 inwardly toward each other .on thqpphorizontal lane and thencedownwardly and outwar y, roviding par# allel horizontal grooves 15 orcoperation with said shoulders 15. The coperation between the, brace andthe portion of the to`v plate of the tie adjacent the lip 12yconstitutes` a positive lock preventing ther brace from upward oroutward movement from its normal position, the outer end 17 of the bracebeing adapted to abut against the main portion of' the plate at the endof the shoulders 15. The lower inner `portion of the brace is preferablybeveled so as to fit snugly upon the rail base flan e as indicated at18. At 19, in Fig. 6, I ow a detail view of one of a pair of similarrail plates. Each plate comprises amainortion 20 adapted to receive therail direct y thereupon adjacent the seat 11 aforesaid and a shank 21formed preferably integrally therewith extends inwardl therefromapproximatel to the center of t 1e track or mid portion o the tie. Theinner end of the shank is provided with, a horizontal slot 22 formin ashoulder 23. The outer end of the rall plate is rounded or beveled atits lower end as shown at 24, and directly above the bevel at thelongitudinal center of the plate is a seat 25 to accommodate theinterlocking fianges 14 of the 'rail brace.

Patented Nov. 24, 1914..

At 26v I show an inner'rail clamp formed in. any suitable manner uponthe plate 2O and preferabl in a rigid manner. Said clamp 26 is a aptedto conform to and cooperate directly with the inner edge of the -baseliange of the Vrail R when the rail plate is forced upwardly along thetie. The rail of the tie, and the slots 22 of the overlapping Shankscoming .into alinement 'with' each other provide a seat for a peculiarform of locking wedges 27 and 28. 'lhese wedges are arranged in pairsand extend horizontall through slots 29 formed in the side t wa s of thetie.

its

Each wedge comprises a structure heaving one edge 30 substantiallyperpendicular to the axes of the Shanks. and 1s adapted to abut againsta shoulder 23 lof one shank and the end 3l of one of the slots 29 whilethe opposite edge 32 of the wedge shoulder and corresponding point 31 onthe opposite side of the crosstie. l prefer also torovide a lug 33 atthe' large end of 'each we ge at the end of the straight side 30 thereofto lprevent the from being forced too far through A1134,- I

pravide a series of notches along the oblique? side 32 of each wedge,the notches of one wed e being adapted to register with those of t, eother when the wedges are driven wedges in position. Said pin may be inthed0 strength for the block.

home, anda pin 35 is adapted to be 4passed through a pair of saidnotches to lock the form of a bolt havin al nut l36 or other fasteninmeans to ho d it in place. The action o the wedges related, as abovedescribed, to the Shanks of the rail plates causes the lates to beforced a art, each being forced) snugly under its rai and with 'itsclamp 26 grlpping the base `liange as stated, making a rigid connectionfor both sets of clamps and braces.

At 37 I show a cushion in the form preferably of a wooden block which isadapted to be forced through the open end of the tie and beneath themain portion of the rail plate 20. The bevel 24 serves to facilitatetheintroduction of the block without mutilating the block or changingits rectangular form, and hence insurinthe full supporting y driving theblock snu ly into position, it serves as a slightly re 'ent cushion forthe rail supported thereupon through the plate 20. The block may be heldin place by any suitable means such, for instance, as by a spike 38driven through a hole 39 in the top of the tie. A notch M40 at the endof the tie provides means for isoblique to the edge 30. The other wedge,coperaties similarly with the other shankv amarte introducing a crowbaror other implement for the purpose of withdrawing the blockwhen desired.l

Having thus described my invention, l claim as new and desire to secureby Letters Patent 1.
